I have a new Apple Silicon Mac Mini that I'm using for 3rd party kext development for a usb audio interface. I'm trying to launch Startup Security Utility to lower the security policy to allow for kext loading. I get to the view to select the drive to unlock (drive is encrypted) but when I click the "Unlock..." button the system just hangs there. I can move the mouse and the dialog but it never gets to the place where opening the utility is an option.
